  • Patent number: 9649711
    Abstract: A method for electrically contacting terminal faces of two substrates, such as a chip and a carrier substrate, includes two successive phases. In a first phase, the chip is positioned with its terminal faces against terminal faces of the substrate and laser energy is applied to the chip at the rear. In a second phase, a flux medium is applied and laser energy is applied to the rear of the chip to cause reflow. The device for performing the second phase of the method comprises a carrier table and a housing, which form a housing interior with a top side of the carrier table which receives the component arrangement, and a laser light source, which is oriented so that the laser radiation impinges on the rear side of the first substrate.
